In your opinion is it better to run with the threshold off in single frequency?  I have noticed that some guys when in 
iron infested ground will recommend turning the threshold off. Will turning the threshold off make the machine not respond
as well in detecting a target? What is the best way to run it? I hope this is not to much af a loaded question.
